Abstract
The utility model belongs to the technical field of illuminating lamps, in particular to a flame-proof type LED tunnel lamp, and solves the problems that the LED tunnel lamp in the prior art has the disadvantages of unreasonable design and short service life. The flame-proof type LED tunnel lamp comprises an LED light source and a shell for mounting the LED light source, and is characterized in that a heat-conducting base, on which a plurality of LED light sources are ceramic-packaged, is welded with an entire heat-dissipating aluminum substrate which is mounted on the shell. The utility model has the beneficial effects that the heat-dissipating design is reasonable and throughout, the luminous decay of the LED is reduced and the service life of the tunnel lamp is guaranteed.
Description
Technical field
The utility model belongs to the technical field of lighting, specifically is a kind of explosion-proof type LED tunnel lamp, and it can replace the mine explosion-suppression fluorescent lamp, is widely used in that colliery, oil, chemical industry etc. are inflammable, in the explosive atmosphere.
Background technology
As a kind of brand-new lighting engineering, LED utilizes semiconductor chip as luminescent material, directly convert electrical energy into the luminescent device of luminous energy.LED illumination is described as human revolution for the third time of throwing light on owing to have the characteristic of long, energy-conservation, safety of life-span, environmental protection.
But the most of electric energy of LED are transformed conduction heat on the present technical situation.In addition, for illumination, several LED of needs are placed in the module to reach required brightness, a plurality of LED concentrate on and have caused the heat radiation difficulty in the limited space, the led module temperature raises, cause the LED life-span to be reduced, and quicken light decay, the efficient that influences elements such as led driver and the reliability of LED.
Adopt the mining tunnel lamp of great power LED to begin to occur, but because heat dissipation design unreasonable, the whole lamp life-span is difficult to guarantee 50,000 hours.
Summary of the invention
The utility model is unreasonable in order to solve in the prior art LED mining tunnel lamp heat dissipation design, and the problem that service life is short provides a kind of explosion-proof type LED tunnel lamp.
The utility model adopts following technical scheme to realize:
A kind of explosion-proof type LED tunnel lamp comprises led light source, and the housing of led light source is installed, and it is characterized in that the heat-conducting base of some LEDs light sources of ceramic package is welded on a monoblock heat-radiating aluminum plate, and the heat-radiating aluminum plate is installed on the housing.
Aluminium base is furnished with a monoblock circular slab of lead above being.Led light source becomes circumferential to be uniformly distributed on the aluminium base.Aluminium base and housing contact site scribble heat conductive silica gel.The housing upper end is evenly distributed with trapezoidal fin.
The utlity model has following beneficial effect: reasonable fully heat dissipation design, reduced the light decay phenomenon of LED, guaranteed the service life of tunnel lamp.

Among the figure: 1-cap, 2-0 RunddichtringO, 3-housing, 4-cable cover(ing), 5-T type plug, 6-cable gland, 7-cable pressing plate, 8-steel plate washer, 9-circuit installing plate, 10-circuit board, the 11-copper washer, 12-aluminium base, 13-LED light source, 14-glass lamp shade, 15-protection net
The specific embodiment
As shown in Figure 1, explosion-proof type LED described in the utility model tunnel lamp mainly contains compositions such as led light source 13, housing 3, cap 1, circuit board 10, circuit installing plate 9, cable fixture, glass lamp shade 14 and protection net 15.
As shown in Figure 1, circuit installing plate 9 is screwed in housing 3, cable jacket comprises the cable cover(ing) 4 and the steel plate washer 8 of rubber, cable is introduced from cable gland 6 and is connected with circuit installing plate 9 binding posts, screw cable gland 6 and compress cable cover(ing) 4, make cable and cable cover(ing) 4 produce interference, and cable is compressed, make cable be not easy to be stretched with cable pressing plate 7.The other end also with sheath, steel plate washer, the sealing of T type plug, screws gland; Housing 3 is fastening with cap 1 usefulness hex bolts, and cap 1 is added with O RunddichtringO 2.The design of this part makes the utility model product have good sealing, flame proof effect.
As shown in Figure 2, led light source 13 evenly distributes and is welded on the aluminium base 12 of an integral body, aluminium base 12 is bonding with housing 3 usefulness high thermal conductivity coefficient silica gel, the heat that led light source is produced can be very fast pass to housing 3, the design of the trapezoidal fin of large tracts of land can be dispersed in the air heat fast on the housing 3, thereby prolongs the service life of led light source.
This novel flame proof LED tunnel lamp is provided with glass lamp shade 14 and protection net 15, and protection net is fixed on glass lamp shade on the housing boss by screw, is lined with copper washer 11 under the glass lamp shade.This part embodies sealing of the present utility model, flame proof mentality of designing.
